The construction of the following supplementary exercises is based upon the problems discussed in the previous chapter. It is assumed that the student has, by the preceding exercises, gained a knowledge of tools and processes sufficient to enable him to select wisely those which he should use to accomplish certain results; therefore these models are intended to be only suggestive, and it is not necessary to follow the course as outlined. Any model may be selected which is of approximately the same degree of difficulty as those described. Specified exercises will not generally be mentioned, but at each step the previous work should be reviewed, and its application to the work in hand carefully considered. Complete dimensions of models are sometimes purposely omitted, as the student should use his judgment in developing a working drawing from the sketch of each model that he makes. The stock lists are made out for a few of the models simply to indicate the method to be followed in making out the lists for others, and not for the purpose of making the work easy. Unless noted otherwise, the following models may be made of any soft wood. In making them, the student should in each case first make a working drawing, being guided by Chapter II. A stock list should be prepared by the method indicated in those following. The exact dimensions should be placed upon the stock list in the order given, - length, width, and thickness, though in some localities the order is thickness, width, and length. Allowance for working should be made when the stock is cut.
